DESCRIPTION OF THE PREFERRED EMBODIMENTS

With reference to FIGS. 3 and 4 for a chassis door cover switchstructure of the present invention, the chassis door cover switchstructure is a box formed by a casing 1 and a cover 2. In thisembodiment, the casing 1 includes a chamber 11 having an opening 12 forcontaining electronic devices and components, and the cover 2 ispivotally installed to both sides of the opening 12 by a pivot 21, andthe pivotal rotation of the cover 2 allows the cover 2 to be coveredonto the casing 1 to close the chamber 11.

The casing 1 and the cover 2 control the locked status by using acontrol member 3, and the casing 1 includes at least one latch member 13installed at an edge of the opening 12, and the cover 2 includes acontrol member 3 configured to be corresponsive to each respective latchmember 13, so that after the cover 2 covers the casing 1, the controlmember 3 may be pushed to separate or embed the latch member 13 in orderto switch the locked status and the unlocked status of the casing 1 andthe cover 2.

In FIG. 4 as well as FIGS. 6 and 7, the latch member 13 is extended fromthe opening 12 of the casing 1 into the chamber 11, and the latch membercomprises a main body 131 and a stop portion 132, wherein the stopportion 132 is disposed at the top end of the main body 131 and aplug-in space 133 is formed between the stop portion 132 and the mainbody 131, and a socket 134 is formed at a side edge of the main body131. In other words, the plug-in space 133 is formed and extended fromthe socket 134 along a defined moving direction D.

In FIGS. 5 and 5A, the control member 3 includes a switching button 31and a switching plate 32, both coupled to the cover 2. The cover 2 hasan inner side 22 facing the chamber and an outer side 23 facing awayfrom the chamber, wherein the switching button 31 is installed on theouter side 23 of the cover 2, and the switching plate 32 is installed onthe inner side 22 of the cover 2. In this embodiment, the inner side 22of the cover 2 has a groove 221 configured to be corresponsive to eachrespective switching plate 32, and each switching plate 32 is installedin the groove 221. In each groove 221 of the cover 2, a through hole 222is formed along the moving direction D, and each switching button 31 andits corresponsive switching plate 32 are passed through the through hole222 and connected with each other by a connecting member 311 for fixingand combining them as a whole in order to control them to movesynchronously in the moving direction D. Preferably, a pad 33 isinstalled between each switching button 31 and the cover 2. In addition,two positioning holes are formed along the moving direction D in eachgroove 221 and defined as a left positioning hole 223A and a rightpositioning hole 223B respectively, and the left positioning hole 223Aand the right positioning hole 223B are disposed on both sides of thethrough hole 222 respectively.

The switching plate 32 has two positioning portions extended in oppositedirection with each other along the moving direction D and defined as aleft positioning portion 321A and a right positioning portion 321Brespectively, and the distance between the left positioning portion 321Aand the right positioning portion 321B is smaller than the distancebetween the aforementioned left positioning hole 223A and theaforementioned right positioning hole 223B. In this embodiment, theswitching plate 32 and its left positioning portion 321A and rightpositioning portion 321B are made of plastic, so that the leftpositioning portion 321A and the right positioning portion 321B have theelasticity for pivoting with respect to the switching plate 32. Apositioning bump is formed separately at ends of the left positioningportion 321A and the right positioning portion 321B, and the twopositioning bumps are defined as a left positioning bump 322A and aright positioning bump 322B respectively. When the left positioning bump322A and the right positioning bump 322B are pressed at the bottom sideof the groove 221, the left positioning portion 321A and the rightpositioning portion 321B are slightly pivoted with respect to theswitching plate 32 to produce a resilience force for resuming theoriginal position. When the switching button 31 is flipped, theswitching plate 32 is controlled to move as shown in FIG. 6. When theright positioning bump 322B is situated at a position superimposed withthe right positioning hole 223B, the resilience force as shown in FIG. 7drives the right positioning portion 321B to resume its originalposition and drives the right positioning bump 322B to fall into theright positioning hole 223B, so as to provide a positioning effect.While the control member 3 is moving, at most one positioning bump fallsinto positioning hole, so as to achieve the effect of positioning thecontrol member 3.

In FIGS. 5 and 6, the switching plate 32 has a tongue portion 323extended towards the moving direction D, and the tongue portion 323 isdriven and moved by the displacement of the control member 3 in order toenter into or leave from the plug-in space 133 of the latch member 13and switch the locked status between the cover and the casing.Specifically, after the cover is covered onto the casing, the switchingbutton 31 is flipped to move from a first position to the right alongthe moving direction D as shown in FIG. 8 (wherein the first position ofthis embodiment refers to the position when the tongue portion 323 ofthe switching plate 32 is disposed outside the plug-in space 133, sothat the cover 2 and the casing are situated at an unlocked status). Inother words, the tongue portion 323 is extended from the socket 134 ofthe latch member 13 into the plug-in space 133 by the displacement ofthe switching plate 32. Now, the tongue portion 323 is stopped at thestop portion 132, so that the control member 3 cannot leave the latchmember 13 in any direction other than the moving direction D, and thecover is locked to the casing. In addition, the control member 3 can bepositioned when the right positioning bump 322B falls into the rightpositioning hole 223B.

On the other hand, the switching button 31 is flipped to move from asecond position to the left along the moving direction D as shown inFIG. 9 (wherein the second position of this embodiment refers to theposition when the tongue portion 323 of the switching plate 32 isextended into the plug-in space 133 and stopped by the stop portion 132,so that the cover 2 and the casing 1 are situated at the locked status).In other words, the tongue portion 323 leaves the plug-in space 133 ofthe latch member 13 by the displacement of the switching plate 32. Now,the tongue portion 323 is not limited, and the control member 3 issituated at a free status, and the locked status between the cover andthe casing is released. When the control member 3 is situated at thesecond position, the positioning effect is achieved when the leftpositioning bump 322A of the switching plate 32 falls into the leftpositioning hole 223A.
